Our invention relates toe-edge tools, and vhas "among its objects andadvantages the provision of animp'roved scissors Sharpener.,

`In the accompanying drawing: l

Figure l is aside elevational view of my invention;

l Figure 2f is an end view;

Figure 4 is a sectional view along the line `4f-4in1? Figure'l; landFigure 5 is an end view illustrating a scissors blade in position in theSharpener. 'In the embodiment selected for illustration,

'we make use of a metallic strap bent to provide a frame comprising abase I0, an'end wall I2 'i and atop wall I4. The top wall I4 isarrangedin parallelism with the base VIl) and is intercon- -nectedtherewith through the medium of a diagonal wall I6, a wall I8paralleling the base II), and

a narrow end wall 20. One end of the strap is vWelded at 22 to the topwall I4, which wall is ex",- Ytended to provide a prong 24 which servesas a of .a file 30,-with the slots so located as to bring Figure 1illustion, with the edge 34 to be sharpened lying on the file 30 andheld at the proper anglev by the 'wall IB, the latter being preferablyarranged at an angle of seventy degrees to the base Ill, Means :forpressing the blade 32 against the wall I6 to support the blade atthedesired angle comprises v.the end face 42 of the block 36 and thewallI2.

This spring is held in place by a bolt y44 threaded into the block andextending loosely through an opening 46 in theend wall I2.I The bottomface 48 ofthe block 36 rests on'the base I0, and the block is providedwith a groove 50 for loosely receiving the file 30. In Figure 3, thewall I4 is shaped in the nature of a dovetail in cross section for loosereception in a correspondingly shaped groove 52.

Projections 54 are provided on the block 36, which projections aregrooved, as at 56 in Figure l, to facilitate a convenient grasp thereon.In operation, the base Ill may be placed on a table and supported in astationary manner by grasplng the handle 26 in one hand and manipulating'mannen the scissors With the other. The projections 54 are arrangedsuiiiciently close to the handle -26 to lbe accessible by the thumb andforenger of the hand grasping the handle, as when shifting the block toaccommodate placement of the blade.

vTwo plates 58 are attached to the block 36 and extend loosely throughslots 6U in the end wall I2. These plates provide enclosures for thespring 40, in addition to restraining the block from lateraldisplacement. The sides of the block 36 are recessed at B2 for receivingthe extensions `64 so as to bring the plates within the side limitsofthe end Wall. Screws 66 secure the plates to the block. y l

v While the device may be manually supported in a fixed position, theextension provided by the wall I8 permits a clamp to be applied theretoif it-is desired to fixedly secure the device in that The le 30 isremovable and may be shifted from time to time to distribute wearthereon.

Without further elaboration, the foregoing will so fully illustrate myinvention, that others may, by applying current knowledge, readily adaptthe same for use under various conditions of service.
